Q2’26 Sustainability Primary Insights Wrap: Octus’ Data Shows Execution Drives ESG Differentiation Not Disclosure; Growth, Labor, Ownership Structure Shape Performance

Sustainability Analysts: Adrian Cîrjă, Mădălina Necoară, Dylan Collins, Diana Preda

Editor’s Note: This quarterly wrap has been renamed to reflect the rebranding of our product to Sustainability Primary Insights from ESG Primary Insights.

The second edition of Octus’ Sustainability Quarterly Insights offers investors a focused view of Sustainability developments observed among leveraged loan and high-yield bond issuers covered by Octus during Q2 2026. Bringing together primary issuer analysis, sector-level observations and issuance activity across Europe and the United States, the report is designed to help readers distinguish between headline sustainability commitments and the underlying factors shaping issuer resilience, risk and execution.

The analysis is based on the Q2 primary dataset (selected coverage) and does not represent, and should not be interpreted as representative of, broader market-wide trends across all Q2 2026 issuance.

Key Takeaways

• Beyond pledges, issuer differentiation increasingly hinges on execution rather than disclosure alone. The strongest performers combine measurable emissions reductions, high renewable energy shares, workforce stability and formal links between ESG targets, executive remuneration or financing terms, while baseline policy coverage is increasingly widespread and less differentiating.
• Efficiency gains do not necessarily reduce absolute environmental exposure. Within the selected Q2 dataset, acquisitions, production growth, methodological changes and renewable procurement often improved emissions intensity or reported performance without producing an equivalent reduction in physical energy demand or the total environmental footprint.
• Workforce retention is driven more by sector and labor structure than geography. Low turnover is concentrated among issuers supported by collective bargaining, unionized workforces or specialized talent pools, while clinical services continue to face structurally higher attrition linked to staffing shortages and shift-based operating models.
• Ownership influences governance, but implementation determines its effectiveness. Private equity-backed and family-controlled issuers generally show weaker board independence and formal ESG accountability, yet wide variation in diversity, oversight and controversy outcomes indicate that governance structures alone are not reliable evidence of effective execution.
• Q2 shifted the analytical focus from disclosure gaps to execution quality. While Q1 was dominated by incomplete Scope 3 coverage, workforce-diversity constraints and sponsor-backed governance gaps, Q2 focused more on whether environmental progress reflected absolute reductions, how labor structures shaped retention and whether company-level accountability could mitigate ownership-related weaknesses.

This report assesses sustainability performance across 74 primary leveraged loan and high-yield bond issuers in Q2 2026, based exclusively on a selected subset of transactions covered by Octus during the period and not the full universe of new issuance. The analysis draws on issuer disclosures to assess environmental, social and governance outcomes in the context of evolving market conditions. Within the selected dataset, issuers show wide variation in both ESG performance and disclosure quality, including differences in emissions trajectories, employee turnover, board composition and formal accountability mechanisms. This variation reflects differences in business models, ownership structures and sector characteristics, alongside uneven reporting maturity, with important implications for comparability, transparency and the credibility of reported ESG progress.

Q1 vs. Q2 Comparison: From Disclosure Gaps to Execution Quality

Across Octus’ selected quarterly datasets, ESG differentiation shifted from disclosure availability in Q1 to quality, comparability and credibility of reported execution in Q2. Note that Q1 and Q2 evaluated distinct issuer cohorts (73 issuers and 74, respectively) so this shift reflects broader thematic trends emerging from each dataset rather than direct quarter-over-quarter progress or regression among the same companies.

From an environmental perspective, Q1 was primarily characterized by incomplete visibility over value-chain exposure, as only 63% of issuers disclosed Scope 3 emissions and more than one-third of the sample therefore provided no comprehensive view of its total emissions footprint, whereas Q2 allowed the analysis to move beyond the presence of disclosure and assess whether reported improvements reflected durable operational decarbonization. Twenty-four Q2 issuers reported higher Scope 1 and 2 emissions, including 16 whose revenue-based emissions intensity nevertheless declined, demonstrating how acquisitions, production growth, reporting-boundary changes, methodological revisions and renewable energy procurement can improve reported intensity or market-based emissions without producing an equivalent reduction in physical energy demand or the absolute environmental footprint. The central environmental question therefore shifted from whether issuers disclosed material emissions data in Q1 to whether the performance improvements reported in Q2 represented genuine changes in underlying operations rather than the effects of business expansion, methodology or contractual energy sourcing.

The principal social theme also evolved, with Q1 highlighting structural constraints on female representation across STEM-intensive sectors, where limited technical talent pipelines influenced both workforce composition and progression into leadership positions, while Q2 placed greater emphasis on employee retention and the conditions supporting workforce stability. Lower turnover in the Q2 sample was concentrated among specialized or unionized workforces supported by collective bargaining arrangements, while clinical services continued to report structurally higher attrition amid staffing shortages and shift-based operating models, reinforcing the broader conclusion across both quarters that sector characteristics and labor structures were generally more influential than geography alone in explaining workforce outcomes.

Governance findings remained directionally consistent between the two datasets but became more nuanced in Q2, as the pronounced gap identified in Q1 between sponsor-backed and publicly listed issuers across board independence, gender diversity, disclosure and ESG oversight remained visible, while material company-level exceptions demonstrated that ownership structure does not determine governance quality in isolation. Private equity-backed and family-controlled issuers continued to show weaker independence or lower transparency in the Q2 sample, but variation in board diversity, formal accountability and ESG oversight indicated that effective implementation can mitigate ownership-related weaknesses, reinforcing the broader shift toward measurable outcomes and accountability mechanisms as more meaningful differentiators than baseline policies, committee structures or disclosure alone.

Selected ESG Performers: Decarbonization Progress, Resource Efficiency and Governance Differentiation

GHG Emissions Reduction and Science-Based Target Adoption

A distinct group of issuers in the current dataset demonstrates credible decarbonization trajectories through a combination of measurable absolute emissions reductions and science-based target validation in sectors where Octus industry data shows peer adoption remains structurally low.

• Cushman & Wakefield, the U.S.-based commercial real estate services firm, achieved its original 50% Scope 1 and 2 reduction target in 2024, six years ahead of schedule, representing one of the most material target delivery outcomes in the dataset relative to stated ambition.
• WS Audiology, the Danish hearing healthcare group, reduced Scope 1 and 2 market-based emissions by 85% against its base year, supported by a Net-Zero Standard target validated by the Science Based Targets initiative, a credential held by only 16% of Health Care Equipment and Supplies companies in the Octus universe.
• U.S.-based industrial automation and networking company Belden reduced combined Scope 1 and 2 emissions by 48.6% in 2025, exceeding its 25% reduction target ahead of schedule.
• Techem, the German energy services company, holds SBTi-aligned climate targets in an industry where Octus data records only 10.43% of companies at validation stage, with energy intensity declining 42% between 2021 and 2025 providing early evidence of trajectory alignment.
• And French telecommunications infrastructure services company Circet anchors its climate strategy on SBTi-validated 2030 absolute reduction targets in a Construction and Engineering industry where Octus data places peer adoption at 18%.

Renewable Energy Transition

A distinct cluster of issuers in the current dataset has achieved renewable energy shares across total operational consumption that materially exceed sector norms, with several reaching transition rates that represent structural rather than incremental progress.

• VodafoneZiggo, the Dutch telecommunications joint venture, leads the dataset with a 97% renewable energy share of total energy consumption in 2025, alongside a second consecutive EcoVadis Platinum rating placing it within the top 1% of assessed issuers globally.
• Spanish medical technology distributor Palex operates with a 79.2% total renewable energy share, sitting significantly ahead of healthcare distribution peers, while also producing the lowest Scope 1 and 2 emissions intensity among its named peer group.
• Septodont, the French dental pharmaceutical manufacturer, accelerated its renewable energy share to 53% of total energy in 2025 from just 4% in 2022, representing one of the fastest transition trajectories in the dataset.
• Danish biotechnology company Genmab sourced 65% of total energy consumption from renewables in 2025, supported by Energy Attribute Certificates and onsite solar expansion, positioning it above the sector norm for biotechnology issuers.
• And Mehilainen, the Finnish healthcare services provider, achieved a 76% total renewable sourcing share in 2025, driven by renewable electricity procurement across its Finnish and Nordic estate and leading its healthcare provider peers by a wide margin.

Workforce, Governance and ESG Accountability

Across the current dataset, the most material social and governance differentiators are found in safety performance, workforce stability and the structural integration of ESG metrics into remuneration, with meaningful dispersion between issuers that disclose policy frameworks and those that report against specific, measurable targets.

• Archroma, the Swiss specialty chemicals company, reported an LTIR and TRIR of 0.02, against Octus industry averages of 0.48 and 0.80, respectively for the chemicals industry, representing an exceptional safety outcome within a process chemicals manufacturing environment.
• Spanish industrial bakery group MonBake reported employee turnover of 1.8% against an Octus industry average of 17.9% for Food Products companies, underpinned by full unionization and collective bargaining agreements across its production workforce.
• Cushman & Wakefield reports board gender diversity of 75% and executive committee diversity of 58.8%, against Octus industry averages of 27.2% and 21.9%, respectively for real estate services, both figures representing material outliers relative to all named peers.
• Stada, the German pharmaceutical company, ties 10% of the executive board annual bonus equally to a Scope 1 and 2 reduction target and female representation in senior management, with both targets met in 2025.
• Mehilainen, the Finnish healthcare services provider, links interest margins on its syndicated loans to a clinical quality index, public health centre access times and carbon emissions, integrating care delivery outcomes directly into financing cost structures.

Where referenced, industry averages reflect benchmark values calculated across the Octus universe for companies within the same GICS industry, based on the most recent available reported data. These averages are derived from available issuer disclosures and are intended to provide consistent points of comparison across sectors rather than serve as rating or performance thresholds.

Environmental Progress Diverges Across the Q2 Issuer Sample 

Environmental performance across Octus’ selected Q2 dataset of 74 issuers shows that improvements in emissions intensity did not consistently translate into a smaller absolute footprint. Twenty-four issuers reported higher Scope 1 and 2 emissions, compared with 27 recording reductions, while the remaining 23 lacked sufficiently comparable data to establish a clear directional trend. All 16 issuers that lowered their issuer-reported, revenue-based emissions intensity despite higher absolute emissions were included within the increase group, illustrating that intensity metrics can provide an incomplete view of progress where acquisitions, production growth or broader operating footprints increase total emissions.

This divergence was particularly evident among acquisitive and expanding issuers. Phenna Group’s Scope 1 and 2 emissions rose 16.5% in FY’25 while its emissions intensity declined 16.7%, with the company linking the movement to the integration of 25 acquisitions completed during the year. Alvest recorded an 11.6% year-over-year increase in operational emissions between 2023 and 2024 as manufacturing volumes and its AES division expanded, although its emissions intensity was 28% lower than its 2021 baseline. Constantia Flexibles similarly reported a 21% increase in operational emissions in 2025, driven primarily by the consolidation of Aluflexpack AG plants. These examples show that lower revenue-based intensity may indicate that emissions are growing more slowly than revenue or production without demonstrating that the absolute footprint is contracting.

Methodological and reporting-boundary changes also materially affected reported trends. Solenis reported a 24% reduction in Scope 3 emissions between 2024 and 2025, although the decline was about 12% on a like-for-like basis after adjusting for updated raw-material emission factors. Cushman & Wakefield’s disclosed energy consumption fell 69% in 2024, largely reflecting a narrower office reporting boundary rather than a directly comparable reduction across the same operational perimeter. In the opposite direction, MotoGP’s reported organizational footprint increased 379% after its Scope 3 inventory expanded to include additional racing series, transportation and accommodation, while emissions declined by about 5% when assessed using the comparable prior-year methodology. These cases demonstrate why like-for-like information and transparent explanations of methodological revisions are essential when distinguishing reported movements from changes in underlying operations.

Renewable procurement created a similar distinction between lower market-based emissions and lower physical energy demand. Clarios reduced market-based Scope 2 emissions by 22.8% between FY’22 and FY’24 through a nuclear power purchase agreement, renewable electricity contracts and certificates, despite a 6.9% increase in total energy consumption. Nouryon reduced market-based Scope 2 emissions by 7% in 2025 as renewable electricity reached 54% of total electricity consumed, while overall energy use increased 0.6% and location-based Scope 2 remained unchanged. These instruments can materially reduce market-based Scope 2 emissions, but do not necessarily indicate lower electricity consumption or lower emissions associated with the underlying grid mix.

Scope 3 exceeded 75% of total reported emissions for 44 of the 74 issuers assessed, calculated as Scope 3 divided by the sum of Scope 1, Scope 2 and Scope 3, using market-based Scope 2 where disclosed and location-based Scope 2 otherwise. However, inconsistent Scope 3 boundaries and the mixed Scope 2 basis limit direct comparison across issuers. For equipment manufacturers, downstream use-phase emissions were structurally more significant: Category 11 represented more than 78% of Versuni’s total footprint and 85% of Trench Group’s Scope 3 emissions, while Smiths Detection identified use of sold products as its dominant emissions category without disclosing an exact share. These estimates rely on assumptions concerning product lifetimes, customer use and future electricity-grid emission factors, reinforcing the need to assess Scope 3 targets in relation to each issuer’s business model and degree of influence over the relevant emissions source.

Clearer evidence of operational decarbonization was visible where absolute reductions were supported by physical efficiency measures and cleaner electricity sourcing. Schuelke & Mayr reduced Scope 1 and 2 emissions by 22.2% and intensity by 40.4% against its 2021 baseline, supported by steam-generation improvements and 100% renewable electricity at its principal Norderstedt site in Germany, although renewable energy represented a lower share across the wider group. Stada reduced market-based Scope 1 and 2 emissions by 35.5% against its 2020 baseline through renewable electricity procurement, facility-efficiency measures and heat-pump deployment, with renewable electricity reaching 70.2%.

The selected Q2 dataset indicates that evidence of environmental progress is clearest where emissions reductions can be connected to comparable reporting boundaries, lower physical energy demand and identifiable operational measures. Acquisitions, operating expansion, methodological revisions and contractual energy procurement can materially shape reported trajectories, making it necessary to assess not only whether emissions declined, but whether the movement reflects a durable reduction in the issuer’s underlying environmental footprint.

Sector Dynamics and Collective Bargaining Shape Retention

Workforce retention shows substantial variation across the current dataset, with turnover rates ranging from below 2% to above 30% within a single reporting period. This variation appears to be driven more by sector composition and structural labor frameworks than by geography or company-level HR investment. Collective bargaining agreements and full unionisation can provide additional support for workforce stability beyond employer branding or engagement programmes.

MonBake reported turnover of 1.8% compared with an Octus Food Products industry average of 17.9%, with stability supported by a fully unionized workforce operating under collective agreements rather than discretionary retention initiatives. Trench Group reported turnover of 3% against a Machinery industry average of 12.9%, while Palex and Ceva Santé reported 5% and 6%, respectively, compared with Octus averages of 15.9% and 13% for Health Care Equipment and Supplies and Pharmaceuticals. These outcomes also reflect the retention characteristics of specialized roles where expertise may take several years to develop and replace.

The contrast was particularly visible in clinical services, where shift-based working and sector-wide staffing shortages contributed to turnover rates of 22.7% at Almaviva Santé, 21.7% at Affidea and 30.5% at Medicover, all above the Octus Health Care Providers and Services average of 16.7%. In these environments, improvement trajectories may be more informative than absolute levels: Mehiläinen’s four-year decline to 11% in 2025, compared with peers remaining above 22%, suggests active management of a structurally challenging workforce environment.

Geographic differences, often assumed to be a primary driver of labor outcomes given Europe’s stronger regulatory and unionisation frameworks, showed limited explanatory power at the aggregate level. European and U.S.-headquartered issuers in the dataset reported similar simple average turnover rates of 14.74% and 14.23%, respectively, suggesting that sector dynamics and labor structures are stronger determinants of retention than domicile alone.

Where low turnover is supported by collective bargaining coverage and contractual labor frameworks, workforce stability may be more durable than where retention depends primarily on discretionary initiatives that could come under pressure during periods of financial constraint. Approximately 73% of Chemicals peers and 55% of Food Products peers in the Octus universe disclose trade-union non-interference commitments, indicating that formal labor protections are sufficiently prevalent in manufacturing-intensive sectors to provide a relevant point of comparison.

Ownership Structure and Accountability Shape Governance Outcomes 

Ownership is associated with governance outcomes across Octus’ selected Q2 dataset, but does not fully explain differences in board independence, diversity or formal ESG accountability. Private equity-backed and family-controlled issuers generally showed weaker independence or lower transparency, although several exceptions indicate that ownership alone is not a reliable measure of governance quality.

Board independence and disclosure varied materially. Of the 74 issuers assessed, some did not publicly disclose their board composition, while others reported no independent directors. At the upper end, Nouryon, Evertec and Cushman & Wakefield reported independence levels of approximately 87.5%–92%, compared with 12.5% at Ramsay Santé and 20% at TMF Group. Nouryon’s position among the strongest performers despite its private equity ownership further illustrates that company-level governance practices can outweigh ownership structure.

Board diversity followed a separate pattern. Ramsay Santé combined low independence with 62.5% female board representation, while Cushman & Wakefield reported 75%, substantially above the Octus industry average of 27.2% for Real Estate Management and Development. Conversely, several issuers reported no female board members despite stronger representation at executive level, indicating that leadership pipelines do not consistently translate into board composition.

Formal ESG oversight and remuneration links remained limited differentiators. Most issuers assign sustainability responsibilities to existing Audit, Risk or Governance committees, while explicit ESG-linked executive remuneration is uncommon and often narrow in scope. Baseline ethics and compliance policies are now widespread, shifting differentiation toward the effectiveness of implementation and the treatment of issuer-specific risks, including supply-chain due diligence, deforestation and cybersecurity. Governance quality is therefore better assessed through the independence, scope and effectiveness of accountability mechanisms than through ownership, committee structures or policy coverage alone.

Global Uncertainty and Energy Pressures Shape the Q2 Issuance Backdrop

Primary leveraged-loan and high-yield bond issuance in Q2’26 took place against a backdrop of continued geopolitical disruption, renewed energy-driven inflation and increasingly fragmented trade policy, creating an environment in which weaker growth expectations and restrictive financing conditions reinforced uncertainty.

As with Q1’26, the conflict in the Middle East remained the principal source of volatility, disrupting energy markets and keeping prices elevated. The resulting shock increased transportation and input costs, weakened confidence and renewed inflationary pressure, with Europe particularly exposed through its reliance on imported energy.

Trade policy also remained a significant source of uncertainty. The United States expanded sector-specific trade actions covering steel, aluminium and copper, while broader Section 301 investigations increased potential exposure across manufacturing sectors and trading partners. These measures added complexity to supply-chain planning and increased uncertainty around sourcing costs and market access.

These developments weakened the global outlook and interrupted the earlier disinflationary trend. The World Bank lowered its forecast for global growth to 2.5% in 2026, from 2.9% in 2025, as higher energy prices, inflation and borrowing costs weighed on activity. Monetary policy diverged in response: the Federal Reserve and Bank of England held rates steady in June, while the European Central Bank raised its key rates by 25 basis points as the energy shock increased inflationary pressure.

Financial markets remained sensitive to geopolitical and policy developments, although public credit markets proved comparatively resilient and financing conditions stabilized after periods of volatility. Competition from syndicated markets also intensified as lower pricing encouraged some borrowers to move away from private credit, where issuance and fundraising slowed and concerns around liquidity and portfolio quality increased.

Regional divergence remained evident, with the United States maintaining comparatively stronger economic momentum and corporate performance, while Europe faced greater exposure to the energy shock, weaker confidence and renewed monetary tightening. Energy-importing emerging markets also experienced pressure from higher commodity prices, inflation and reduced policy flexibility.

Taken together, Q2 2026 was defined by continued Middle East disruption, elevated energy costs, trade-policy fragmentation and diverging central-bank responses, shaping a volatile but functioning backdrop for primary market activity and reinforcing the importance of issuer exposure to energy, supply chains and refinancing conditions.
